Postgres problems on the CI server

Hi all,

ActiveRecord Postgres tests are failing on the CI server as follows:

1. ForeignKeyFixturesTest crashes the postgres process (literally, a segfault). 2. Subsequent tests fail because they cannot get a database connection while Postgres is recovering from the crash. 3. Once pg_ctl restarts postgres processes, all remaining tests pass.

Google seems to think that Postgres 8 segfaulting on PPC Macs is not unheard of... Few quick remedies I tried (restart, recompile, update the client, recreate the database files etc) didn't work.

For the time being, I just commented out the section that runs test_postgresql within the build script. If anyone is interested in troubleshooting Postgres segfaults, post me please.
